4 Infra-Red Technology

Infra-Red Transmission

The SZI 1015-T is a powerful infra-red radiator with integrated modulator. Within a cordless IR transmission system, it transforms the electrical signal of the audio source into invisible infra-red light and radiates it into the room. In contrast to radio transmission systems, infra-red transmission is restricted to the room, therefore, other systems can be used in neighbouring rooms without any risk of interference.

The SZI 1015-T modulator/radiator is switched on by the audio signal. Please use the balanced XLR-3 input socket for connecting the SZI 1015-T to the audio source.

To connect additional SZI 1015 radiators, use 50 Ω RG 58 co-axial cables with BNC connectors. Alternatively, you can also use cables without connectors with the barrier strip (RF output terminal).

Wideband

Wideband transmission systems are used for transmitting high-quality audio.

Areas of Application

Any application which requires quality audio transmission, for example systems for the hard- of-hearing in churches and theatres.

Propagation of Infra-Red Light

The propagation of the IR light emitted by the SZI 1015-T modulator/radiator is comparable to that of normal daylight or artificial (lamp) light. Therefore, the infra-red light is subject to similar conditions when it falls onto different surfaces and materials:
